Core Viewpoint - Chinese researchers have developed an efficient and stable semi-transparent photoelectrode device that significantly enhances the rate of water oxidation reactions and improves hydrogen production efficiency from solar water splitting, further advancing the development of more efficient and durable "artificial leaves" [1] Group 1 - The research team from Tianjin University has created a semi-transparent indium sulfide photoanode that possesses unique transparent characteristics [1] - This device not only enhances the water oxidation reaction rate but also allows some sunlight to penetrate to the photoelectrode, reducing ineffective energy loss from sunlight [1] - The research addresses the conflict between the opacity of metal layers and the barrier to charge carrier transport across interfaces [1] Group 2 - The findings have been published in the international academic journal "Nature Communications" [1]
